About this tool
This MOV to MP4 converter turns Apple QuickTime videos into MP4 files that open everywhere. MOV is the format iPhones, iPads, Macs and QuickTime Player record and save, and it is not always welcome on Windows PCs, Android phones, smart TVs or upload forms. MP4 is. The conversion runs in your browser, so your video is never uploaded.
How to convert MOV to MP4
- Drop the MOV file on the page or click to choose it.
- The panel shows the codecs inside the file and whether it can be copied without re-encoding.
- Click Convert to MP4. For HEVC videos, pick High quality or Balanced first.
- Check the preview and download the MP4.
Why MOV to MP4 is often instant
MOV and MP4 are close relatives: MP4 was built on Apple's QuickTime file format. When a MOV holds H.264 video and AAC audio, which is the case for most screen recordings, older iPhones and phones set to Most Compatible, the converter only moves the streams into an MP4 container. Nothing is re-encoded, so it takes seconds and the picture is identical.
| Your MOV | What happens | Speed |
|---|---|---|
| H.264 video (Most Compatible, screen recordings) | Copied into MP4, no quality loss | Seconds |
| HEVC / H.265 (iPhone High Efficiency) | Re-encoded to H.264 MP4 | About real time or faster |
| ProRes (pro cameras, Final Cut) | Not supported by browsers | Export H.264 from your editor |
Tips for iPhone videos
- Want instant MOV to MP4 next time? On iPhone, Settings > Camera > Formats > Most Compatible records H.264, which this tool copies without re-encoding.
- Portrait videos keep their rotation, so they play upright in the MP4.
- Spatial or Dolby Vision HDR videos may look flatter after re-encoding to H.264, because most players show SDR.
- Big file? After converting, run it through the video compressor to share it in chats or by email.
Private by design
Your MOV is read and converted on your own device with the browser's WebCodecs engine. Nothing is sent to a server, which matters for family videos and work recordings. Want only the soundtrack? Use the MP4 to MP3 converter, which also reads MOV files.

Frequently asked questions
How do I convert a MOV to MP4?
Drop the MOV file on this page and click Convert to MP4. If the video uses H.264, it is copied into an MP4 in seconds. HEVC iPhone videos are re-encoded to H.264.
Does converting MOV to MP4 lose quality?
Not for H.264 MOV files: the video and audio are copied as they are. HEVC videos must be re-encoded; the High quality preset keeps them very close to the original.
Why won't my iPhone MOV play on Windows or Android?
Recent iPhones record MOV files in HEVC (H.265), which many PCs, TVs and apps cannot play without extra codecs. Converting to H.264 MP4 fixes this.
Is my video uploaded?
No. The MOV is converted in your browser using your device's media engine. It never leaves your phone or computer.
Can I convert MOV to MP4 on iPhone or Mac?
Yes. Open this page in Safari or Chrome on a recent iPhone, iPad or Mac, choose the video and convert it. No app is needed.
Are ProRes MOV files supported?
No. Browsers cannot decode Apple ProRes. Export an H.264 version from Final Cut Pro, iMovie or your camera app instead.
